2.7 About the Software with your PRORXB The PRORXB has two software elements:

� Firmware that runs inside the device on the boards.

� Control Pages that you access using your web browser on your Windows PC.

About the Firmware Although much of the unit is built up of hardware components, many of the sophisticated features are implemented in firmware running on a Field Programmable Gate Array (FPGA) inside the device.

When you need to perform an internal software upgrade we provide an installer pack which contains all the code you’ll need to do this easily.

About the Control Pages The software tools provide users a convenient access to the most common features and functions of the device. All software tools are implemented as a web interface. The advantage of a web interface is that it is independent from the user’s operating system and doesn’t require any specific software on the host PC.

The Control Panel on the front of the unit gives access to many of the features of the radio but for more sophisticated operations and configuration tasks you’ll connect up a PC running a web browser to access the Control Pages on your PRORXB.

The Control Pages enables you to set up sixteen presets in the radio and have control over many parameters of the unit.

Here’s what one of the PRORXB Control Pages look like:

4. Setting up your PRORXB 4.1 Connecting the Antennas This topic describes connecting systems designed mainly for transporting the RF signals. Of all the variables affecting single-channel radio communications, the one factor that an operator has the most control over is the antenna. With the right antenna, an operator can change a marginal net into a reliable net.

There are eight antenna interfaces located on the rear panel of the PRORXB receiver.

Note: If you have four-way diversity PRORXB then you must connect four antennas to achieve best performance from the four-way diversity receiver system.

If you have six-way diversity PRORXB then you must connect six antennas to achieve best performance from the six-way diversity receiver system.

If you have eight-way diversity PRORXB then you must connect eight antennas to achieve best performance from the eight-way diversity receiver system.

Before you Begin You’ll need:

� 2, 4, 6 or 8 downconverters that match the frequency range you want to receive.

� 2, 4, 6 or 8 antennas that match the frequency range of your downconverters.

Step 1: Select your Downconverters All PRORXB receivers use downconverters to lower the frequency from microwave (L, S and C-Band) to an Intermediate Frequency (IF) between 51 and 858MHz that the on-board tuners in the receivers can use.

It is important to select the correct downconverter for the microwave transmission frequency you are planning to receive. Downconverters have a label to help you select the correct unit.

If you are using long cable runs from the base of the downconverter to the rear panel of the PRORXB, you may need to select a high gain version of the downconverter to deal with the RF losses in the long cable.

Step 2: Attach the Antennas to the Downconverters 1. Connect each antenna directly to the TNC jack on the top panel of each downconverter.

2. Do not over tighten the antenna – hand tight only!

Step 3: Set Antenna Polarization 1. COFDM links are very robust and are tolerant to changes in antenna position, however, it

is important to try and keep the antennas in the same plane if possible.

2. The antennas used with the COFDM links are normally linearly polarized.



000-083 R1.3.1 2013-08-22


Step 4: Attach IF Cable to the Downconverter 1. Connect the TNC plug on the IF Cable to the TNC jack on the bottom panel of each

downconverter.

2. Do not over tighten the TNC connector – hand tight only!

Step 5: Attach IF Cable to the PRORXB Connect the BNC plug on the IF Cable to the BNC jack on the rear panel of the PRORXB.

Next Steps Connect AC Power.

6. Advanced Operation 6.1 About Encryption The target is focused on intercepting your radio signal. To do this, all that they need is a radio receiver that operates in the same mode and on the same frequency you are using to transmit. The mere fact that you are operating gives them valuable information. It tells them that you are in the area and by the number of stations operating on the same frequency they can estimate the size of the operation against them. If your radio net is operating in the clear, the target specialists can see or hear exactly what is being transmitted for even more information. When analysing the traffic patterns, the target can work out which station is the net control station and identify the headquarters.

6.2 Setting up Encryption If the AES scrambling option has been purchased for the SOLO system in use, then it is possible to encrypt the link. Both AES128 and AES256 are licence-controlled features. You’ll need to encrypt the traffic leaving the transmitter and set up the receiver for decrypt.

Note: The word Encryption applies to the whole process of encryption and decryption. We’ll just use the word encryption for this receiver manual even though what is actually going on here is a decryption process.



� The correct license loaded on the PRORXB for Encryption.

� A laptop connected to the PRORXB configured to browse the Control Pages.

Step 1: Select the Encryption Mode 1. Click on the Configuration tab.

6.1 About Streaming Over IP Note: This section is relevant only to customers that have the Streaming licence loaded onto their PRORXB unit.

Streaming is the transmission of digital audio or video or the listening and viewing of such data without first storing it.

The PRORXB supports:

� Raw Multicast streaming

� RTSP/RTP streaming.

6.2 Configuring UDP Multicast Streaming When you have got a Video or Audio service into the PRORXB, you may want to stream that information down a fixed IP link.

For multicast streaming the transport stream video data is transmitted over the Ethernet network by means of multicasting i.e. continuous real-time streaming of packets accessible to any PC connected to the network.

It is therefore possible for more than one connected PC to view the streamed data simultaneously.


� To have connected your PC to the PRORXB using IP.

� To be logged on to the PRORXB unit.

� The PRORXB must have a Streaming licence installed.

� Have a video transmission being received on Demod 1 of your PRORXB.

Step 1: Open the Global Settings Tab 1. Click on the Global Settings tab.

2. Find the Streaming Settings Pane.



000-083 R1.3.1 2013-08-22


Step 2: Configure the IP Settings Pane - Gateway For multicast operations it is very important that you configure the gateway in the IP settings pane even though we might not have a gateway in our network.

1. You must use an IP address in the same network range as the PRORXB and for simplicity; we recommend you use the actual PRORXB IP Address for your Gateway too.

Figure 6-4 Configure the Gateway in the IP Settings Pane

Step 3: Configure the Streaming Settings 1. Check the Streaming Enable checkbox.

2. In the Streaming Mode box select UDP Multicast.

3. In the Streamer Select box choose the source you want to stream (Demod 1 in my example).

4 Constellation DVBT:

QPSK, 16QAM, 64QAM

Narrowband/UMVL:

BPSK, 8PSK, QPSK, 16QAM

This field indicates the OFDM constellation being received.

QPSK-less user data, more robust, more range.

16QAM-more user data, less robust, less range.

The mode is automatically detected and is simply displayed here. You can’t change it other than at the transmitter.

Narrowband/UMVL:

1/3 or 2/3

This field indicates the forward error correction (FEC) rate which is being applied. Think ‘data bits/all bits’

1/3 means 1 bit out of 3 bits is data and therefore 2 bits are used for error correction.

Little user data means less picture quality, but more error correction means a more robust signal and therefore more range.

2/3 means 2 bits out of 3 bits are data and therefore 1 bit is used for error correction.

More user data means better picture quality, but less error correction means less robust signal and therefore less range.

The mode is automatically detected and is simply displayed here. You can’t change it other than at the transmitter.

1 Video PID Default or 0x0020 to 0x1FFE

Each table or elementary stream in a transport stream is identified by a 13-bit packet ID (PID). This is set at the transmitter.

2 Audio PID Default or 0x0020 to 0x1FFE




000-083 R1.3.1 2013-08-22



3 PCR PID

PCR=Program Clock Reference

Default or 0x0020 to 0x1FFE

Each table or elementary stream in a transport stream is identified by a 13-bit packet ID (PID). This is set at the transmitter. Used to sync the audio and video. The PCR keeps the system clock synced. If the clock starts to drift, it is rectified using the PCR value.

4 Audio Bitrate 64, 96, 128, 160, 192, 224, 256, 288, 320, 352, 384, 416 and 448kbits/s are examples of MPEG L1 bit-rates.

000-083 R1.3.1 2013-08-22



1+6 Presets

If you select Manual it means you will have to type in the LO Frequency and LO Side in the next two fields yourself. You might do this for an unusual frequency that requires an odd downconverter.

If you select UHF it means you don’t really need a downconverter because the receiver is UHF anyway. There may still be an amplifier up near the antenna though.

The easiest thing to do is select your downconverter from the list. Then the LO Frequency and LO Side will be filled in for you. Check the label on your downconverter to see which model you have.

2+7 LO Frequency (MHz)

1880 or any valid downconverter frequency.

All our receiver units use downconverters to lower the frequency from microwave (L, S and C-Band) to an Intermediate Frequency (IF) between 51 and 858MHz that the on-board tuners in the receivers can use.

We get this information from the downconverter frequency and side table in Appendix D – Reference Material.

3+8 LO Side Low or High We need to set which side (of the expected incoming frequency) the LO frequency will be.

In my example the incoming frequency I want to receive is in S-Band, 2.25GHz to 2.65 GHz. I’ve selected a DC-225265 downconverter whose LO Frequency is 1880MHz. Now, 1880MHz is lower than 2.25GHz, so I set the LO side to be Low.




000-083 R1.3.1 2013-08-22



4+9 LNB Power On or Off The downconverters up on the mast need power. We send this up the IF line. We call it LNB power and here is where you turn it on.

LNB=Low Noise Block.

You may want to turn LNB power off if you are using a third party downconverter that has its own power supply for example.

5+10 LNB Voltage 9V or 12V When unit is fitted with latest tuner PCBs, the LNB voltage is selectable.

11 LNB Gain Offset

9 typically, but any value to suit the downconverter you are using.

Most downconverters introduce gain to the RF path. A DCB-200250 for example introduces 9dB in its standard gain version and 19dB in the high gain version.

To make sense of the signal strength numbers you need to apply this correction.

12 Individual LOs Checked or Unchecked

When unchecked the LO Frequency and LO Side apply globally to all downconverters attached to the receiver.

When checked, new fields open up to enable you to set individual LO Frequencies and LO Sides for each downconverter. This means you could have one half of the antennas set up for S-Band and the others, L-Band.

Table 7-15 – Downconverter Settings Pane Key

Step 3: Check the Individual LOs Checkbox When checked, the extra fields which enable individual LO Frequencies are displayed. In addition, you’ll find a checkbox which enables you to invert the COFDM spectrum.



000-083 R1.3.1 2013-08-22


Screenshot: Downconverter Settings Pane, Individual LOs Checked

Figure 7-21 Downconverter Settings Pane with Individual LOs Checked


1 LO Frequency (MHz)

1720 or any valid downconverter frequency.

All our receiver units use downconverters to lower the frequency from microwave (L, S and C-Band) to an Intermediate Frequency (IF) between 51 and 858MHz that the on-board tuners in the receivers can use.


2 LO Side Low or High We need to set which side (of the expected incoming frequency) the LO frequency will be.




000-083 R1.3.1 2013-08-22



3 Invert Checked or Unchecked

Checked=Inverted

Unchecked=Normal

All Cobham equipment should use normal mode. The receivers can be used with other manufacturer’s products and sometimes this requires us to change the polarity to inverted to match this third party equipment.

Table 7-16 – Individual LO Settings Key

Step 4: Configure the IP Settings Pane

Screenshot: IP Settings Pane

Figure 7-22 IP Settings Pane


1 DHCP Enable

(Dynamic host configuration protocol)


When checked the PRORXB is given an IP address by an external DHCP server.

In managed networks which use DHCP address allocation this option should be selected. In networks that are manually managed (or do not feature a DHCP server), users may prefer to assign an IP address manually.



000-083 R1.3.1 2013-08-22



IP Address Example:

192.168.2.65

If the PRORXB is not automatically acquiring its IP address via a DHCP server then a fixed IP address needs to be assigned to the unit

Enter an IP address for this PRORXB in the IP address text box. It can be any class of network you choose.

Network Mask Example:

255.255.255.0

The network mask allows a network administrator to break a network into smaller more efficient subnets to prevent excessive numbers of IP packets being routed through the network. This is normally defined by the network administrator

Enter a subnet mask in the Network mask text box.

Gateway Example:

192.168.2.254

A default gateway is used by a host when an IP packet's destination address belongs to someplace outside the local subnet. The default gateway address is usually an interface belonging to the LAN’s border router.

We recommend you leave the gateway at the same setting as the IP Address.

Note, for correct streaming operation, a valid Gateway address within the IP subnet range must be set, either manually or via DHCP.

Table 7-17 – IP Settings Pane Key



000-083 R1.3.1 2013-08-22


Step 5: Configure the Streaming Settings Pane

Screenshot: Streaming Settings Pane

Figure 7-23 Streaming Settings Pane


1 Streaming Enable

Checked or Unchecked Switches the streaming feature on or off.

Note: The PRORXB must be licensed for Streaming. If it is not, you won’t be able to enable Streaming. In addition, for correct streaming operation, a valid Gateway address within the IP subnet range must be set, either manually or via DHCP.

2 Stream Mode UDP Multicast or RTSP Multicast or RTSP Unicast

Select the streaming mode you want to use.



000-083 R1.3.1 2013-08-22



3 Streamer Select

You choose the source that will provide the stream from this box.

Demod 1 for example means the stream will come from the first receiver channel.

4 Multicast Address

239.16.33.254 This text box enables you to change the multicast address used by the unit. The default value is 239.16.33.254. It is also possible to Unicast by specifying a valid destination IP address within the local subnet range.

5 Multicast TTL 1 to 255

Default is 10

This is the multicast time to live value. Default 127.

6 Multicast Port 10000

Range available is 1-65535

Protocols like TCP or UDP use port numbers in the header to direct traffic around the network. Low port numbers are used by computer systems for predefined tasks. For example SMPT (for your email service) uses port 25.

A good rule is to use numbers above 10,000 to avoid conflict with existing services.

When you set up a port number on several computers on a network they will all listen for packets directed to that port.

The default values are 10000 and 10001.

7 Multicast Service Name

Up to 20 ASCII characters.

The defaults are MPEG2-TS and MPEG2-TS2.

This is an identifier for the service.

8 Multicast ToS

The priority for the Multicast can be set here.

DVBT

UMVL

Choose the modulation bandwidth you want to use.

UMVL- Ultra Mobile Video Link – licence dependant bandwidths.

UMVL is a mix of technologies between DVBT and Narrowband. It is optimised for use in high speed mobile environments (like car racing for example).

UMVL is also excellent when you are using high frequency (4 GHz and above) transmissions.

4 DVBT Carrier Mode

2K or 4K If you selected DVBT as your Modulation Type earlier, you can now select how many carriers will be used.

2K=About 2000

5 ASI Output

The source for the ASI output is selected here.

For example if you choose Demod 1, then this will provide an ASI signal to the ASI Out port.

If you choose Remux, the ASI Output will be made up of whatever you configure in the next field, Remux Input.

6 Remux Input

This field enables you to select what you want to go into the Remux. You can combine sources to be remuxed into a single ASI stream.

For example, Demod 1+ASI in would enable you to have received pictures being combined with a signal from the ASI input port, all being sent to the ASI Output port.

For correct operation all PIDs present in the input streams must be unique.



000-083 R1.3.1 2013-08-22



7 Remux Bitrate 5.00 If you have selected Remux in ASI Output (item 5 in this table) earlier, then this field will become active and will enable you to set the bitrate for the Remux stream leaving the ASI Output port.

You may have remuxed two video signals together which you are then planning to transmit forwards. You could configure the Remux Bitrate to suit your transmitter bandwidth then ensure the two signal you are going to Remux will fit into that space.

For correct operation, the bitrate must be equal or higher than the combined bitrate of all input streams.

4 Bandwidth DVBT:6, 7 & 8MHz

Narrowband: 2.5MHz

1.25MHz

625kHz

DVB-T bandwidths (normally used for broadcast)

Cobham narrowband (normally surveillance use)


5 Guard Interval Narrowband: 1/16 or 1/8

DVBT:

1/32, 1/16, 1/8, 1/4

The guard interval which is being applied to the narrowband mode in use.

The guard interval is a deliberate extension of the RF symbol period to give immunity to reflections.

1/16, short extension, deals with fast reflections, more data, less range.

1/8, long extension, deals with slower reflections, less data, more range.

6 Polarity Normal

Inverted

Auto

All Cobham equipment should use normal mode. The receivers can be used with other manufacturer’s products and sometimes this requires us to change the polarity to inverted to match this third party equipment.

If you select Auto the receiver will attempt to automatically select the correct format for you.

You must be in RTSP mode to use Elementary streams.

Encoder A processor in a video transmitter which converts analogue video from a camera to digital data.

F Means…

FEC Forward Error Correction is a system of error control for data transmission, whereby the sender adds redundant data to its messages, also known as an error-correction code. This allows the receiver to detect and correct errors (within some bound) without the need to ask the sender for additional data. The advantage of forward error correction is that a back-channel is not required, or that retransmission of data can often be avoided, at the cost of higher bandwidth requirements on average. FEC is therefore applied in situations where retransmissions are relatively costly or impossible.

Signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is.

Shannon Limit The Shannon limit or Shannon capacity of a communications channel is the theoretical maximum information transfer rate of the channel, for a particular noise level.

Signal In electronics, a signal is an electric current or electromagnetic field used to convey data from one place to another. The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams.

Streaming Streaming is the transmission of digital audio or video or the listening and viewing of such data without first storing it.

T Means…

Tx A transmitter is an electronic device which, usually with the aid of an antenna, propagates an electromagnetic signal such as radio, television, or other telecommunications.

T Means…

TNC The TNC (threaded Neill-Concelman) connector is a WKUHDGHG�YHUVLRQ�RI�WKH�%1&�FRQQHFWRU��7KH�FRQQHFWRU�KDV�D��ƻ�impedance and operates best in the 0–11 GHz frequency spectrum.

Transport Stream (TS)

Transport streams: These streams can contain several MPEG-2 content channels and associated audio. All the channels are multiplexed together, allowing the receiver to choose which to play back.

U Means…

UDP User Datagram Protocol (UDP) Sometimes called fire and forget because there is no dialog between the sender and receiver. If the receiver does not get a packet, the sender will never know. However, UDP is very efficient when there is little chance of errors (like in your LAN), or when TCP would provide "too late" delivery.

USB Universal Serial Bus

Unicast Unicast is simply sending packets from one source to one destination. For example, from one web server to one (or each) person viewing a page on a web browser.

V Means…

VHF Very High Frequency – 30 MHz to 300 MHz

V Volt.

Viterbi Decoder A Viterbi decoder uses the Viterbi algorithm for decoding a bit stream that has been encoded using forward error correction based on a Convolutional code.

W Means…

Watt The watt (symbol: W) is a derived unit of power in the International System of Units (SI). It measures rate of energy conversion. One watt is equivalent to 1 joule (J) of energy per second.

Waveform Signal shape.

12. Appendix E-Remote Control Guide This section describes the control protocol used on the RS232 interface for controlling the Pro-Rx.

12.1 About the RS232 Control General Principles The physical interface is RS232 but this can be converted to RS485 with an external adapter where multiple units are controlled over one RS485 bus.

Normal operation involves sending a packet from the control device (normally a PC) to the device being controlled. If the packet satisfies an address integrity check, then the controlled device will action the command and send a reply.

For compatibility with modems an ASCII style protocol is used.

Ports are set for 115200 baud, 8 bits, No parity, 1 stop.

12.2 About the Command Packet Structure ASCII Value Notes

STX 02h Start byte

0-9 30h-39h 4 byte unit address. In range 0-9999

R 20h-7Eh 1 byte command type. r read, w write

ABCD 20h-7Eh Command –four byte mnemonic

; 3Bh Separator

PQR 20h-7Eh Data –Optional, variable length

; 3Bh Separator

X 20h-7Eh Sum Check

ETX 03h End byte

12.3 About the Reply Packet Structure ASCII Value Notes

STX 02h Start byte


R 20h-7Eh 1 byte command type. r read, w write

STX 02h Start byte



000-083 R1.3.1 2013-08-22


ASCII Value Notes


Z 20h-7Eh Status BYTE

PQR 20h-7Eh Data –Optional, variable length

; 3Bh Separator

X 20h-7Eh Sum Check

ETX 03h End byte

The Sum check byte is the summation of all bytes in the packet, not including the start and end bytes. Higher order bytes are ignored and the final byte result is modified to prevent ASCII control characters being sent. Bit 7 (highest) is forced high.

The Status byte will indicate if the command was performed OK, or will indicate an error.

ASCII Meaning

1 All OK

E General error, command could not be actioned.

Typically E will be returned if the message is formatted incorrectly (separators in wrong place) or if commands are in upper case, or if commands do not match against the allowed list of commands, or if the checksum is wrong.

Addresses in the range 0001 to 9998 are for general use. Address 0000 is reserved and 9999 is a broadcast address. i.e. any device will reply to this address. Its reply will contain its own specific address.

All data in the transmitter and receiver is stored as one of 5 data types, Double, String, List, Integer or HexInteger. The data type dictates the contents of the data section of the reply.

� List – 1 byte for sending. Value is hexadecimal coded as ASCII. 2 byte reply. Reply represents index into original choice list. e.g. Reply 02 indicates entry 2 in original list.

� Float - variable length. Reply always contains decimal point and 4 decimal places. Can have 1 to 3 digits before decimal.

� Integer - 6byte reply. integer value with stuffed with preceding zeros. e.g. GOP reply 000012 = GOP length 12

� String - Variable length. Reply is string excluding null terminator

� HexInteger – 8byte Hex reply.

12.4 About the Programming Model The control commands work on four sets of parameters:



000-083 R1.3.1 2013-08-22


6. Global parameters which apply to all configs

7. Config parameters which apply to one specific config

8. Status Parameters which are read-only

9. Specials which have unique actions.

To make changes to the settings on the board for Global and Config parameters, they have to be loaded into a “scratch” area. Once in the scratch area changes can be made to the parameters. To make the changes permanent the scratch area has to be saved.

To edit a config you have to load it into scratch by specifying the config number you want to edit. A simple example or changing input frequency is shown below: (<C> represents the checksum)

<STX>0001wload;1;<C><ETX> “Load config 1 into scratch area”

<STX>0001wdipf;2360.00;<C><ETX> “Change input frequency to 2360”

<STX>0001wsave;1;<C><ETX> “Save scratch to config 1”

The config you edit can be different from the currently active config. This means you could edit config 8 in the scratch area and then save it back while config 1 was active. If you edit the active config in scratch, when you save it back it will automatically action any changes. To find the config number currently being edited in scratch, perform an rload command.

The same process applies to Global Settings except that no config number needs to be supplied and the commands change to “wloau” and “wsavu”. When editing globals if the changes are saved they are actioned immediately.

Please note that when issuing read and write commands to Global and Config parameters they always read and write to the scratch area.

The load and loau commands can also be used like a reset if any changes need to be cancelled, i.e. If the user backs out of an edit menu before saving.

Status parameters are always current and not affected by loads and saves.

Specials are actioned immediately.
